Energy Absorbing Manholes
When a hydraulic jump is needed in your flow, a TRACOM Energy absorbing manhole is the easiest solution. A simple drop in place design allows for easy installation saving time and headaches. A baffle slows the flow before being redirected back into piped flow. These energy absorbing manholes can be necessary before flumes or weirs to keep flow subcritical and smooth.
Energy Absorbing Manholes provide an easy-to-install, drop-in-place flow metering solution. Tracom’s fiberglass superstructure is lightweight and quick to bring into service.
Energy Absorbing Manhole Benefits
Our Energy Absorbing Fiberglass Manholes are made from Polyester Resin with Polyester Gel Coating, giving excellent corrosion resistance as a minimum. Energy Absorbing Manholes can be customized to use the right material for your application, including VinylEster Resin or a Resin-rich veil in lieu of gel coating.
Standard design calls for flanged and/or sleeved pipe connections outside. Tracom only uses the highest quality flanges, typically made from Hetron 922 Resin. Tracom flanges are 3rd party rated to conform to PS 15-69 & ASTM D5421. Inlets and outlets are completely customizable from height and center offset to pipe size. Whether you need a flanged connection or a pipe stub, anything is possible to get you what you need.
Energy Absorbing Manhole Installation
When you purchase an Energy Absorbing manhole from Tracom, you’re purchasing a water-tight product straight from the factory. Installation is quick, leaving penetration work to our team. Tracom personalizes your flanges and stubs for extreme ease of installation. Prevent expensive mistakes originating from field-assembled manholes, and use a Tracom Energy Absorbing Manhole for your application.
Energy Absorbing Manholes arrive ready to set-in-place; outside are “ANSI 150lbs pattern” flanges or PVC pipe stubs with flexible sleeves for pipe attachment, as well as a polystyrene pad to place under the manhole when mounting. Inside is an OSHA compliant ladder and 2” NPT coupling penetration for wiring runs.
Tracom Energy Absorbing Fiberglass Manholes come water-tight, so you can easily isolate your access point from groundwater. Filling the void space below your deepest stub-out with grout (or sand topped with grout) provides weight to counter ground water buoyancy.
